Depending on setup effectiveness, Rapax One (1J spring) can give more then 1J (1,2 for example). In that case, just pull the bolt and leave spring for 1 day, after that, try again and if needed just cut 2 coils.

If you have less Joules then you should just add spacer on a spring guide and you are good to go.

We remind you that J is measuring just with heavy bb´s and not with 0.2. Please adjust hop-up for best flight path before measuring.

The lighter pull of these springs compared to standard ones means that you will need to exert less effort to achieve more joules, making them a popular choice for airsofters. Additionally, the use of the same materials and manufacturing processes for all springs ensures consistency and reliability in their performance.

The tempering process is madeto ensure a long lifespan and minimal loss of FPS/joules over time, providing consistent power for your airsoft sniper replica. The tight tolerances in diameter also help to prevent the “twang” sound often associated with lower quality springs. Lastly, it’s important to remember to apply grease to the spring or spring guide before installation to ensure smooth operation.
